I HENRY S. HALLWOQD, OF COLUMBUS, OHIO, ASSIGNOR TO THE CITY NATIONAI:

BANK, OF COLUMBUS, OHIO.

CASH-REGISTER,

To all whom it may concern:

Be it known that I, HENRY S. HALLWOOD, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented a certain new and useful Improvement in Cash-Registers, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

The broad principle of this invention is shown and claimed in my LettersPatent 1,078,920 filed Nov. 4, 1899; 1,085,680 filed Sept. 1, 1900; and845,634 filed Oct. 22, 1906.

The present improvement relates to specific details of a simplifiedconstruction adapted to perform similar functions and produce the sameresults.

The particular object of this invention is to simplify the interlocksshown and described in the Letters Patent to Edward J. Von Pein#938,527, November 2, 1909, in which a very large number of togglejointed devices are shown to lock the department registers, the grandtotal register, the main operating shaft, and all actuating mechanismmoved thereby against operation until four separate locks have beenreleased by a predetermined sequence of key setting operations in which,the middle series must always be operated last, always after the valvekeys, and always after the pinch lever carried by the selective registerlever.

I11 registers of this type the key board is arranged with the value keyson the right,

and the selective register keys one for each register on the left,labeled with letters for clerks or words for departments,,but theidentification keys, which may be labeled with letters or words, arebetween the selective register keys and the value keys, and this centerseries no matter how labeled,are normally ineffective and functionlessuntil the pinch lever has been; pinched and a value key depressed beforean identification key or register is rendered effective. V

This invention provides for placing all the register actuating mechanismunder control' of the two setter dogs herein shown 1 whereby theactuating mechanism will not tion.

departments or both. The various selective registers are normallymovable and one is always in position for the next registration, but allof them are inoperative for'registra tion purposes until both of thedogs have had a tail pushed down by both a value key, and anidentification key. It is immaterial, however, whether the labels bearletters or words, but under all conditions, a selective key must be usedfor changing a register and its indicator with corresponding type intoindicating, adding and printing position, an identification key mustalso be used for indicating, printing and releasing a dog, anda valuekey must also be used before a complete registration and record ispossible, and thus each clerk is compelled to operate both a value andan identification key be fore a new transaction can be indicated,registered and recorded.

The pinchless lever herein shown when between stations prevents thedepression of an identification key and the release of the machine, anduntil a register is in proper position to receive the next registration,but under no circumstances can foolish indications,registrations, orrecords be made such as are now possible on all registers of the 500class. T

It is obvious that these separate and independent dogs compel thedepression without sequence of both a value key and an identifying key(labeled with a word or initial) before'any indication, registration orrecord is a view of the left side of a part of a cash registercontaining my invention.

Fig. 2 is a transverse section 011 line 11 of Fig. 3.

Fig. 3 is a plan view of the parts shown in Figs. 1 and 2.

Fig. 4 is a detail in horizontal section on line 2--2 of Fig. 2.

Fig. 5 is a front elevation of Fig. 3 and shows the indicators B,registering wheels D.

Fig. 6 is a view similar to Fig. 1.

Fig. 7 is a plan view of Fig. 6.

. Fig. 8 is a sectional view of the recorder shown in Fig. 13 of theHallwood Patent 84:5634.

This invention differentiates from the device described in claim 62 ofthis applicants Patent 1078920 in which there are three species of keysfor numbers, letters and words, two of which unlock the main operatingmember, thereby creating an incomplete indication and record.

But to compel the use of all three species and thereby a completeindication, registration and record, in numbers, letters and words thethree cycle interlocks shown described and claimed in Patents 1085680and 8523634, are so correlated and co-active as to compel the operationof a key in three species.

In this invention, there are three species also but the locks areindependent and purposely designed to be responsive to many claims in1085680 and to 73 and 77 of 84563 1, so as to be protected thereby.

In the above described drawings 1 represents a bank of value keys-onefor each denomination. 2 represents a bank of identifying keys. 3represents a series of identifying characters by which are determineddifferent positions of adjustment of the register selecting lever 3 Theseveral banks of keys and the series of identification characters beforementioned are arranged concentric to a shaft 1 which is supported ateach end by side plates in the usual manner as shown in Von Pein938,527. Detent frames 5 are mounted on the shaft 4.- and are operatedby the keys in the usual manner. 6 represents the main driving shaft towhich power is applied either by a hand crank (not shown) through thegear 7 mounted thereon, as shown in the patents referred to, or by anelectric motor 7 through the worm wheel 8 and bevel gears 9.

Mounted on the main drive shaft 6 are disks 16 one at the rear of theidentifying key bank and the other at the rear of the group of valuekey-banks. A notch 15 is formed in each of the disks 16 adapted toreceive the free ends of dogs 13 which are fulcrumed on the shaft 12.The dog 13 of the identifying bank extends forward of the shaft 12 andis formed with a beveled end which is adapted to be engaged by a stud 10projecting from the side of the de tent frame 5 of said identifying keybank 2.

The dog 13 of the value key banks is formed as a bridle which extendsacross the said value key banks. A lever 11 having a shoulder 11 isfulcrumed on the shaft 12 in the rear of each value bank 1. The for wardend of said lever having a beveled face similar to dog 13, adapted to beengaged by the stud 10 on the detent while the shoulder engages theforward edge of the bridle bar and oscillates it when the for ward endof the dog is depressed.

The two levers 17 are fulcrumed on a cross bar 18 of the register frame,and one end of each is adapted to bear on one of the contact bars 19which are included in the electric circuit 7 controlling the motor 7,the opposite end of each of said levers 17 is adapted to be engaged byan extension 20 011 the dogs 13 in such a manner that when a dog 13 islifted out of the notch 15, the free end of a lever 17 is depressed.

A group of registers 21 for either clerks or departments is mounted on areel which is adapted to be turned by the lever 33 to bring the desiredregister to operative position as shown in said Von Pein patent.

This lever is provided with a spring bolt 24: which, when the lever isin proper position, is engaged by one of a series of notches 25 formedon the register index frame. These notches are so formed as to give onlyslight resistance to the movement of the lever from one notch toanother. To prevent the identifying keys from being operated while thespring bolt 24 is out of a notch, a plate 26, having notches 27, isadapted to embrace the lever 3 when set in a proper position. This platelies on the periphery of the selective index adding frame and is given alateral movement, by the pins 28 and the slots 29.

This lateral movement of the plate 26 is caused by the depression of anyone of the identifying keys 2, the cross pins of which extend laterallyand bear against the inclined edge 30 of a segment plate 31 having slots32 by which it is supported and guided by the pin and the rock shaft 34.

The rock shaft 34 is supported by the selective register index andidentifying key frames and carries a rock arm the free end of which isconnected to the plate 31 by a pin, and is rocked when the plate 31 israised by the depression of any key 2. AIL other rock arm 35 is fixed onthe shaft 34 adjacent to the register index frame, and its free end isconnected to a bar 37 which projects upwardly and parallel to the plate26. Said bar 37 connects two levers 38 which are fulcrumed on pins 39projecting from the under side of a cover plate 40. On the free ends ofthe levers 38, a pin 41 projects into a slotted opening 12 in the plate26.

The construction being such that when the levers 38 are moved, the plate26 will be forced toward the lever 3" and hold it' in one of thenotchesl27, and it is equally obvious that if the plunger 24 is not inone offthe notches 25 that all of the keys 2ewill be-locked againstdepression. I

, When the key lever 3 is setzin the desired position (for a repeatsale, *itrneed not be touched) one or more value he so and anidentifying keyare depressed, whereby the dogs 13 are raised out of thenotches 15 of of the disks 16, and the extensions are caused tooscillate the levers 17. to depress the bars 19 against contact points,and thus complete the circuit and start the motor. The construction issuch that the circuit will not be completed untilboth-bars 17 are incontact, and thus the driving shaft 12-is prevented from rotation ifeitherrone of the disks islocked by itsdog, thereby making it compulsorytodepress both a valueand an identifying key before the machine can beoperated, or a department key made efi'ectual for registration purposes.i

,It will thus be apparent that in this improvement I havev not departedfrom the spirit of my former inventions herein cited, but that I havegreatly improved'uponthe two, three and more cycle locks shown in theprior art by means ofiwhich the construction is greatly simplified andtheresult desired is secured bythe least possible number a of elements,the primary object being to comseries 2 of keys ma pel the use of both avalue'key and an identifying key, before. a new transaction can beindicated, registered and recorded.

While inthe drawing the series of keys 2 have been. shown as transactionindentification keys and the lever '3 and indentification tablets 3'areshown as clerk identification means, it is obvious that theseidentification elements may be transposed and the be employed'foridentifying clerks and t e-lever'and its coacting parts may be employedfor identifying transactions. This is merely a matter of changing thedesignation or tablets and necessitates no change in-the mechanism oroperation. L s

In the appended claims the value keys, the transaction keys and theclerks keys or lever have been collectively termed operation determiningelements inasmuch as 7 they control and determine the performance of theoperating mechanism. They have been separately classified as amountdetermining elements and identification determining elements, thelatterterm being applicable whether the "keys or the lever are employedfor designating either clerks or transactions. Having thus describedinvention, what In. I desire to secure Letters E atent for, is expressedin the following claims: I
